IMPROVEMENT IN CONDENSING CARDlNG-ENGINES.

Specification forming part of Letters Patent No. 35,114, dated April 29,1862.

To @ZZ whom it 11m/y concern/.V

Be it known that I, ISAAC STEAD, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented some new anduseful Improvementsin Condensing Carding-Engines for Cardin andCondensin g Fibrous Substances; and I do hereby declare that thefollowing is a full, clear, and exact description of' the constri'lctionand operation of the saine, reference lbeing had to the annexeddrawings, making a part of' this specification, in which- I `ignre l isaside view; Fig. il, an end view. Fig. 3 is an enlarged sect-ion oli'(flotter-shaft and traversing-cam. Figs. l and i5 are enlarged sectionsof the revolving toot-hed fiber-separa tor. Fig. 5V is an enlargedsection of the collar-doffing roller.

My improvements belong to that class of cards called corulensers.7

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation by referring to theaccompanying` drawings.

A is the cylinder, and (I the frame, which are made in the ordinarymanner.

I3 is the dofi'er, which I propose to make larger than than the usualsize. For afortyeight-inch cylinder I use a thirty-six-iuch-diameterdoffer, the doffer being thirfysix inches wide on the face and coveredwith a continuous piece of wire fillet. I now divide the face of thedoffer into seventy-two part-s, (two to the incli,) or as seen in Fig.2, which is divided into twenty-four parts. The cylinder delivers thefibers to the doffer, covering the whole face. It is necessary that thefibers should be separated at the points where the wire is divided. I dothis by the revolving` toothed fiber-separator I, which is constructedas seen in Fig. o'.

M is a shaft turned to lit` the holes in the collars N N and circularplates L. At I the collar is forged fast and turned true. One of thecircular plates is slipped on against the collar, and then one of thecollars N turned to suit the width of the rings or divisions on thedoffer; then a second circular plate, and so on, till you have as manycircular plates as you have rings on the doffer. The whole is firmlyfastened by the last collar, which has a thread cut in it and acorresponding thread cut on the end of the shaft. The last collar actsas a nut and the whole is screwed tight. The circular plates can be madeof sheet-steel about one-sixteenth of an inch in thickness. The teethshould be about eight to the inch of circumference.

The fiber-separator is hung in bearings in the plate R, Fig. l.Thisplate is hung on the dolfer-shaft and steadied by the pins a a d.rlhe fiber-separator is set so that the saws or pla-tes will passbetween the rings on the doffer and separate the fibers. All the fibersthat the separator takes :from the doffer are collected by the stripperS, as seen in Fig. 1, and carried back to the cylinder. The stripper isa plain roller covered with wire fillet and set so as to work betweenthe fiber-separator and cylinder.

Having described the construction and operation of the fiber-separator,I will now describe the construction of the collar-doffing roller K, asseen in Figs. 2 and (section) 5.

I make a pla-in shaft, as seen in Fig. 5. The collars o o o are made tofit tight on the shaft K. By referring to Fig. 2 it will be seen that Ihave four rollers and six collars on each roller or shaft. The collars oo o can be made of wood and covered with cloth, or they may be made ofmetal, leather, or india-rubber. To operate my doiin`g-roller on athirty-six-inch wide doffer with seventy-two rings or divisions, I maket-he collars one-half-inch wide and eighteen collars on each roller orshaft. I set them as seen in Fig. 2. The first collar to the left on thebottom roller takes the slubbing off of the first ring on the left ofthe doffer, and the first collar on the next roller above the slubbingoff of the second ring, and the first collar on the third roller theslubbing off of the third ring, and the first collar on the fourthroller the slubbing off of the fourth ring, and the second collar on thebottom roller the slubbing off of the fifth ring or division of thedoffer, and so on, as seen in Fig. 2. The doffing-rollers deliver theslubbing to the rubbers in the usual way. Should it be desirable to makecoarser work and only use three spools, one dofng roller can bedispensed with by putting fty-four divisions or rings on the doffer andmaking the collars on K the doffing-rollers to suit the width of therings on the doffer. The fiber-separator inust also be adjusted to suitthe rings on the doffer. The dofng-rollers and fiber-separator erm beadjusted to suit any kind of work, coarse or line, with two spools 4ormore. At those points on the doier where the fiberseparzitor separatesthe wire the dofer will not take the iibers from the oylindein Y To renredy this and prevent the Iibers :from colleoting,` at any part of thecylinder, I cause the doffer to traverse the face of lthe Cylinder.

In Fig'. 2 it will be seen that the doffer libersepamtor anddofng-rollers are all Conn eeted or hung on. the doffer-shaft by theplate R. On the end of the dolfer-sh'aft, Fig. 2, is the traversin g-emnE, (more plainly seen in Fi 3.) The stand F is rinly fixed to thecard-frame,

and as the dofer revolves the @am E @mises the doffer to traverse theffice-Cylinder for the above-described purpose.

I Claiml. The revolving toothed Cylinder in Coinbination with the doiingcylinder B oi' :t con d en si ng @aiding-engine, as forming` afibersepairzrtor, as described in. my specification.

2. The stripper S, in combination with the revolvil'ig toothedcylinderI, for the purpose of removing' the fibers which may collect on theteeth and omrying iheni baek to the main cylinder, as described in niyspecification.

ISAAC STEAD.
